Default Re: An opportunity to be SMUG

It would indeed - probably a bit too late now. Instead, the capitalised units are the ones named after somebody. So the capitalised base units are amp (A), kelvin (K). Second is s (though I personally write sec so as never to confuse with siemens S); metre is m; then we move to two-lettered base units, kilogram is kg; candela is cd; and then to three letters, mole being mol. All the other SI units are derived units, usually a single capital letter when named after someone but occasionally two (e.g. Hz, Wb).

Siemens incidentally I have never used, nor mho (which there was a period when the abbreviation was upside-down capital omega). I prefer to write mA/V instead, as every conductance I've used is mutual conductance, of valve (occasionally transistor). And then, if load is in kilohms, multiply the two together to get gain (wow! That's brought just about right back to the OP's first post!).
